Hardwood floors are one of Toronto's most valued home features — and one of the most common. From century homes in The Annex and Cabbagetown to 1970s-era splits in Scarborough and Etobicoke, hardwood has been Toronto's default flooring material for generations. The good news: unlike other flooring types, hardwood can be brought back to life through refinishing. For a full comparison of all flooring options, see our Complete Home Flooring Guide Toronto 2026.
Refinishing your existing hardwood is almost always cheaper and faster than replacing it — and with the right contractor, the result looks brand new. This guide covers real 2026 costs, the step-by-step process, finish options, and how to know when refinishing isn't enough.

How Much Does Refinishing Cost?
Hardwood floor refinishing in Toronto costs $3.00 to $6.00 per square foot in 2026, depending on the condition of the floors, the finish you choose, and the contractor's experience.
Cost Breakdown
| Service | Cost/Sq Ft (CAD) |
|---|---|
| Basic refinish (sand, 1 coat stain, 2 coats poly) | $3.00–$4.50 |
| Premium refinish (sand, stain, 3 coats poly) | $4.00–$6.00 |
| Dustless refinishing | $4.50–$7.00 |
| Oil finish (Rubio Monocoat or similar) | $5.00–$8.00 |
| Staircase refinishing | $25–$50 per step |
| Board replacement (damaged sections) | $8–$15 per sqft |
Total Project Cost Examples
| Home Area | Square Footage | Estimated Cost (CAD) |
|---|---|---|
| Condo (1-bed) | 500–700 sqft | $1,500–$4,200 |
| Townhouse (main floor) | 600–900 sqft | $1,800–$5,400 |
| Detached (main + upper) | 1,200–2,000 sqft | $3,600–$12,000 |
What Affects the Price
- Condition: Heavily damaged floors with deep scratches, stains, or warping require more sanding passes and possibly board replacement.
- Species: Softer woods (pine, fir — common in older Toronto homes) need gentler sanding and more care. Harder woods (oak, maple) are more forgiving.
- Stain colour changes: Going from dark to light (or vice versa) requires deeper sanding to remove the existing stain.
- Access difficulty: Tight rooms, closets, stairs, and areas around fireplaces increase labour time.
- Floor area: Larger projects get better per-sqft pricing due to setup efficiency.

The Refinishing Process
A professional hardwood floor refinish follows these steps:
Step 1: Preparation (Day 1 Morning)
- Move all furniture out. Remove or protect baseboards. Counter-sink protruding nails.
- Seal doorways with plastic sheeting to contain dust.
Step 2: Sanding (Day 1)
Three progressively finer grits (36→60→100+) remove old finish and create a smooth surface. Edge sander handles perimeter; hand scraper works corners.
Step 3: Staining (Day 1–2)
If you're changing the colour, stain is applied after sanding. The stain penetrates the raw wood, giving it the desired tone. Common choices in Toronto homes:
- Natural: No stain — showcases the wood's natural colour. Popular for white oak.
- Golden/honey: Classic warm look. Common in 1990s-era Toronto homes.
- Grey/weathered: Modern trend, especially in downtown condos.
- Dark walnut/espresso: Rich, dramatic look. Hides imperfections well.
- Custom mix: A good refinisher can blend stains to match a specific colour.
Stain dries for 4–8 hours before the first coat of finish.
Step 4: Finishing (Day 2–3)
Two to three coats of finish are applied, with light sanding (screening) between coats. Each coat dries for 2–4 hours before the next is applied.
Step 5: Curing (Day 3–5)
The floor is walkable in socks after the final coat dries (typically 24 hours). Full cure — when you can place furniture and rugs — takes 3 to 5 days for polyurethane and up to 7 days for oil finishes. Avoid shoes, heavy furniture, and area rugs during the curing period.

Oil vs Polyurethane
This is the biggest decision you'll make after choosing to refinish. Both have devoted fans — here's the honest comparison.
Polyurethane (Water-Based)
- Appearance: Clear, glossy to satin finish. Does not yellow over time (unlike oil-based poly).
- Durability: Creates a hard plastic film on the surface. Excellent scratch and wear resistance.
- Drying time: 2–4 hours between coats. Full cure in 3–5 days.
- Odour: Low VOC. Minimal odour during application.
- Maintenance: Easy — sweep and damp mop. The surface film repels moisture and stains.
- Repair: Difficult. Scratches through the finish show as white marks. Spot repair is not seamless — eventually the entire floor needs re-sanding and recoating.
- Cost: $3.00–$6.00/sqft (standard refinishing option).
Oil-Based Polyurethane
- Appearance: Warmer, amber tone that deepens over time. Traditional hardwood look.
- Drying time: 8–24 hours between coats. Full cure 5–7 days.
- Odour: Strong VOC — ventilation essential. Cost similar to water-based.
Hardwax Oil (Rubio Monocoat, Osmo)
- Appearance: Matte, natural look. The wood feels like wood — no plastic film.
- Durability: Penetrates the wood rather than sitting on top. Less scratch-resistant than poly, but damage is less visible.
- Maintenance: Requires periodic refreshing (every 1–3 years in high-traffic areas). Spot repair is possible — just reapply oil to the affected area. No full re-sand needed.
- Odour: Very low VOC. Environmentally friendly.
- Repair: The biggest advantage. Scratches and wear marks can be fixed locally without refinishing the entire floor.
- Cost: $5.00–$8.00/sqft. Higher upfront, but ongoing maintenance is simpler and cheaper.
Which to Choose?
| Priority | Best Choice |
|---|---|
| Maximum durability, low maintenance | Water-based polyurethane |
| Traditional warm look | Oil-based polyurethane |
| Natural feel, easy spot repair | Hardwax oil |
| Low odour / eco-friendly | Water-based poly or hardwax oil |
| Budget | Water-based polyurethane |

Dustless Refinishing
Traditional sanding generates enormous amounts of fine wood dust. "Dustless" refinishing uses industrial vacuum systems attached directly to the sanding equipment, capturing 95–99% of dust at the source.
Advantages
- Dramatically less mess: No dust coating every surface in your home.
- Healthier: Less airborne particulate for you and your family.
- Faster cleanup: The contractor finishes and leaves a clean workspace.
The Catch
- Not truly dustless: It's more accurately "dust-reduced." Some fine dust still escapes, particularly during edge sanding and hand scraping.
- Costs more: Expect a 25–40% premium over standard sanding ($4.50–$7.00/sqft vs. $3.00–$5.00/sqft).
- Not always necessary: If the area is empty and sealed off from the rest of the home, standard sanding with proper containment is perfectly fine.
Our Recommendation
For occupied Toronto homes — especially condos where dust spreads easily through HVAC systems — dustless refinishing is worth the premium. For vacant or fully contained spaces, standard sanding saves money without meaningful inconvenience.

How Many Times Can You Refinish?
This depends on the type and thickness of your hardwood:
- Solid hardwood (3/4" thick): Can be refinished 8 to 10 times over its lifetime. Each refinish removes approximately 1/32" of wood. With typical use, a 3/4" solid hardwood floor can last 100+ years with periodic refinishing.
- Engineered hardwood: Most products have a 2–4 mm wear layer on top, allowing 1 to 3 refinishes. Thinner wear layers (2 mm) may only support one careful sanding. Check the manufacturer's specifications. For more on engineered hardwood vs. other options, see our comparison guide.
- Thin solid hardwood (3/8"): Only 1 to 2 refinishes before the tongue-and-groove joint is compromised.
How to Tell If Your Floor Can Be Refinished
A simple test: remove a floor register (heat vent) and look at the cross-section of the flooring. If you can see significant wood thickness above the tongue, refinishing is safe. If the wear layer looks thin or the tongue is nearly exposed, consult a professional before committing.

When to Replace Instead
Refinishing isn't always the answer. Replace your hardwood when:
- 1. Structural damage: Boards are cupping, crowning, or buckling due to moisture damage. Sanding can flatten minor cupping, but severe warping indicates subfloor moisture problems that must be addressed — the boards need replacement.
- 2. Extensive water damage: Dark, blackened boards from prolonged water exposure are damaged beyond refinishing. The staining has penetrated deep into the wood grain.
- 3. Too many refinishes: The floor has been refinished so many times that the nails or tongue-and-groove joints are exposed. Further sanding would compromise the floor's structural integrity.
- 4. Species or style change: You want to switch from narrow-strip oak to wide-plank white oak, or from softwood pine to a harder species. Refinishing can change the colour but not the wood itself.
- 5. Subfloor issues: If the subfloor underneath is uneven, rotting, or compromised, the flooring should be pulled up, the subfloor repaired, and new flooring installed.

FAQ
How much does it cost to refinish hardwood floors in Toronto?
Hardwood floor refinishing in Toronto costs $3.00 to $6.00 per square foot CAD in 2026 for a standard sand-and-finish job. Dustless refinishing runs $4.50–$7.00/sqft. Oil finishes (Rubio Monocoat) cost $5.00–$8.00/sqft. A typical 1,000 sqft Toronto home costs $3,000–$6,000 for a full refinish.
How long does hardwood refinishing take?
The process takes 3 to 5 days from start to furniture replacement. Sanding takes 1–2 days, staining and finishing take 1–2 days, and curing requires 1–3 additional days. The area should be off-limits during this time.
Can you refinish hardwood floors without sanding?
"Screen and recoat" applies a new topcoat over the existing finish after a light abrasion (screening). It works only if the existing finish is in good condition with no deep scratches or bare spots. It costs about $2.00–$3.00/sqft and extends the finish life by 3–5 years. It's not a substitute for a full refinish on worn floors.
Is it worth refinishing hardwood floors before selling?
Yes. Freshly refinished hardwood floors are one of the highest-impact, lowest-cost improvements for Toronto home sellers. Real estate agents consistently rank refinished hardwood as a top "must-do" before listing. The $3,000–$6,000 cost typically returns 3–5x in perceived home value.
